Abstract: Purpose: The aim of this study was to evaluate and compare the effect of changing either the amount of mandibular protrusion or the vertical jaw separation on apnea/hypopnea index (AHI) and snoring index (SI) In patients suffering from obstructive sleep apnea (OSA). Material and methods: Twenty fully dentulous patients suffering from obstructive sleep apnea were randomly divided into two equal groups; group I: In which patients were treated by screw-type adjustable two-piece mandibular advancement devices (MADs) that were initially adjusted at 50% (1st stage), then readjusted at 75% (2nd stage) of the maximum protrusion, and group II: in which patients were treated by two ready-made bite openers (BOs); the first provides 7 mm (1st stage), while the second 11mm (2nd stage) vertical jaw separation.
